HARNESSFRAME FOR LOOMS.

Specification of Letters Patent No. 28,270, dated May 15, 1860.

To all 'whom fit may concern:

Be it known that I, J AMES GREENHALGH, of Pascoag, in the county ofProvidence and State of Rhode Island, have invented a new and usefulImprovement in the Harness- Frames of Looms; and I do hereby declarethat the following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming part of thisspecification, in which- Figure l is a front view of a harness frame,constructed according to my invention. Fig. 2 is a transverse verticalsection of the same in the line zu, of Fig. l. Fig. 3 is a horizontalsection of the upper heddle bar. Fig. 4 is a transverse section of theupper heddle bar, on a larger scale than the other figures. Fig. 5 is afront view of a frame of the old construction.

Similar letters of reference indicate corresponding parts in all theigures.

My invention consists in a certain construction of the frames for thereception of wire heddles, whereby the ends of the wires of the heddlesof one frame are prevented catching against the next frames or theirheddles and the heddles are kept stretched better than by the usual modeof securing them.

To enable others skilled in the art to make and use my invention I willproceed to describe it with reference to the drawings.

A, A are the heddle bars, and B, B, the end-pieces of the frame, bywhich the said bars are connected, and kept at the proper' distanceapart. The bars A, A', are made each of a straight strip of sheet'ironof the requisite length, and of suitable width, bent transversely into anearly elliptical form, as represented in Figs. 2 and 4, or to aquadrangular form leaving a narrow longitudinal opening a, between theedges. The endpieces B, B, consist of pieces of flatbar-iron, and areinserted in the ends of the bars A, A', and secured therein by rivets b,b, the narrow openings a., a, being brought opposite each other, that isto say, to the bottom of the upper bar A, and to the top of the lowerbar A. Each bar has a recess e, cut in its inner side to make anopening, such as is shown at c, in Figs. 2 and 3, the said recessesbeing both at one end of the frame as shown in Fig. 1.

CZ, d, are two straight fiat rods, one placed loosely inside each heddlebar and extending not quite the whole length of the interior thereof.These rods may be inserted in the heddle bars at the ends thereof beforethe end-pieces are put in to make the frame, or may be made thin enoughto pass through the slots a, a, after the frame is complete.

C, C, are the heddles each made in the usual way of a single piece ofwire folded in the middle of its length and twisted to form the .eye 71,in the middle, and to form loops f, and g, at the top and bottom for therods el, d, to pass through. The loops g, are completed by twist-ing theends of the wire together, as shown in Figs. l and 9..

To secure the heddles in the so constructed frame, the rods d, cl, arefirst placed inside the heddle bars and their ends brought into therecesses e, e, and the heddles are then placed, one at a time, betweenthe said recesses, as shown in red outline at the left hand of Fig. 1,and their loops f, g, slipped into the wide openings c, c, at the backof the said recesses, and passed over the ends of the rods, after whichthey are slid along the rods in the narrow openings a, a, from whichtheir loops f, g, cannot come out, as they are kept open by the rods d,d. The twisted ends of the wires which complete the loops g, g, beinginside of the lower heddle rail, are protected and prevented catchinginthe adjacent frames, and in this consists a great advantage over theold mode of securing them by rods vl, i, passing through fixed eyes j,j, in the rails, as shown in Fig. Besides this advantage the strain ofthe heddles being sustained by the bars A, A', enables them to be keptextended better than they are by the rods z', i, which receive theirstrain in the old mode of securing them.

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination of the hollow heddle bars A, A', and the rods d, d,inserted within the said bars to secure the loops at the ends of theheddles, substantially as herein described.
